Abstract: Abstract of the Disclosure The present invention relates to a process for the reinforcement of geological formations and loose rock and earth masses by introducing, into the cavities of the geological formations or rock or earth masses which are required to be reinforced, reaction mictures based on organic polyhydroxyl compounds and organic polyisocyanates which react to form polyurethanes, which process is characterized in that the polyisocyanate component used is a polyisocyanate mixture  containing from about 10 to 80%, by weight, of 2,4'-diisocyanato-diphenylmethane.   The present invention also relates to a two-chamber cartridge suitable for carrying out the process according to the present invention.   This cartridge comprises two chambers separated from each other, one containing a polyisocyanate component and the second chamber containing a polyol component, the quantitative propotions of the two components being calculated so that when the cartridge is destroyed, a reaction mixture which reacts to yield a polyurethane is obtained, characterized in that the polyisocyanate component used is a polyiso-cyanate mixture containing from about 10 to 80%, by weight, of 2,4'-isocyanato -diphenylmethane.

Abstract: ABSTRACT OF THE DISCLOSURE        An intake regulator suitable for use in an auto-motive internal combustion engine, selects to recirculate the exhaust-gas to an intake passage or to introduce air for dilution of the air-fuel mixture, depending on the specific operating conditions.  Smooth shift between the recirculation of the exhaust-gas and the introduction of air by orifices and check valves in the pneumatic intake regulator reduces the formation of nitrogen oxides to a minimum, while keeping the impairment of fuel cost and driveability to a minimum.

Abstract: ABSTRACT           A hatch cover having a locking mechanism comprising a single hand wheel with a shaft threaded to the cover for limited up and down movement as the hand wheel is turned.          A locking strap is hinged on one side of the hatch cover, releasably locked on the other side and has an opening through which the shaft extends.  The locking strap is confined between the hand wheel and a thrust washer attached to the shaft in such a fashion that rotation of the hand wheel in one direction produces contact between the locking strap and thrust washer to force the cover downwardly.  Rotation in the other direction lifts the hatch cover to permit unlatching of the locking strap and access to the hopper.

Abstract: METHOD OF CASTING ALUMINUM BASE ALLOY SHEET AND PRODUCT           ABSTRACT OF THE DISCLOSURE         In continuous casting of aluminum base alloy in sheet form where the alloy comprises small but effective amounts of silicon, iron, manganese, magnesium and copper, an objectionable amount of edge cracking has occurred in the product.  This has necessitated side trimming the sheet with the resultant cost of the edge shearing operation and wasted energy in melting the scrap.   Applicants have dis-covered that by increasing the iron and manganese contents of the alloy and decreasing the silicon and magnesium con-tents, edge cracking can be eliminated or reduced to the point where edge shearing can be eliminated or significantly reduced.
